Abstract

This document provides information about character encoding KOI8-U

(KOI8 Ukrainian) wich is a de-facto standard in Ukrainian Internet

community. KOI8-U is compatible with KOI8-R (RFC1489) in all

Russian letters and extends it with four Ukrainian letters which

locations are compliant with ISO-IR-111. The official site of KOI8-U

Working Group is http://www.net.ua.

IntrodUCtion

This document provides information about character encoding KOI8-U

(KOI8 Ukrainian) widely used in Ukrainian Internet community for mail

and news exchange as well as for presentation of WWW information

resources in Ukrainian language.

Originally, specification of proposed standard koi8-u was officially

adopted by the conference of Postmasters of Ukrainian Internet

Service Providers in Slavsk in Autumn of 1992 presented by Igor

Sviridov from Kiev and Stas Vorony from Kharkiv. Later in June 1995

this specification was completed with UKRAINIAN GHE WITH UPTURN.

KOI8-U (KOI8 Ukrainian) is a de-facto standard supported in many

operation systems and Internet user applications including encoding

tables, fonts, locale support for many operating systems and

environments.

MIME character set name: koi8-u

Relation to other RFCs

This standard is based on several published standards: RFC1489 (it

is fully compatible in all Russian letters), RFC-1345, ISO-IR-111,

ISO 10646.

Compatibility with other character sets

The lower part of the KOI8-U Ukrainian Character Set is a complete

copy of ASCII, just as it's used in KOI8-R and other non-ASCII

codepages.

The upper part of the KOI8-U Character Set contains all Russian

letters defined in KOI8-R and four Ukrainian letters (#164, #180 -

ukr. ie, #166, #182 - ukr. i, #167, #183 - ukr. yi, #173, #189 - ukr.

ghe with upturn) which locations are compliant with ISO-IR-111.

BOX DRAWINGS elements in the other positions (that are not used by

Ukrainian letters) are the same as in KOI8-R character set. List of

all differences between KOI8-R and proposed KOI8-U is given in

APPENDIX A.

Specification of the upper part of KOI8-U codepage

The description of all characters of upper half part of KOI8-U

codepage is given according to ISO 10646 Unicode Character Set (UCS).

KOI8-U charset table in RFC1345 format is given in Appendix B.
